The Back Door to Love -Me and My Straight Friend-

I've had a crush on my best friend Yuya for the longest time. It would have stayed a secret, too, if it hadn't been for how stupid he can be! He kept asking to see my butt, and since I couldn't turn him down, I ended up showing him everything... So, I'm on my back with my legs wide open, exposing myself to him, and he ends up touching me. What was supposed to be "just looking" gradually escalates, and before I know it, Yuya and I are both overwhelmed with pleasure. Surely love can't blossom between a gay guy like me and a straight guy like him... just because I showed him my butt...!
